1. A method for determining camera parameters for a digital image comprising:
identifying a digital image captured via a camera device with camera parameters;
generating an edge map by detecting edges within the digital image;
generating a vanishing edge map by weighting the edges of the edge map based on whether the edges correspond to one or more vanishing lines of the digital image; and
estimating, utilizing a geometric model and the vanishing edge map, the camera parameters for the digital image.
